Individual and combined effect of organic eutrophication (DOC) and ocean warming on the ecophysiology of the Octocoral Pinnigorgia flava [PDF]
PeerJ, 2023 Dissolved organic carbon (DOC) enrichment and ocean warming both negatively affect hard corals, but studies on their combined effects on other reef organisms are scarce. Octocorals are likely to become key players in future reef communities, but they are

Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals [PDF]
Royal Society Open Science, 2023 Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont ...

Wild Bitter Melon Extract Regulates LPS-Induced Hepatic Stellate Cell Activation, Inflammation, Endoplasmic Reticulum Stress, and Ferroptosis. [PDF]
Evid Based Complement Alternat Med, 2021 The activation of hepatic stellate cells (HSCs) is a key component of liver fibrosis. Two antifibrosis pathways have been identified, the reversion to quiescent‐type HSCs and the clearance of HSCs through apoptosis. Lipopolysaccharide‐ (LPS‐) induced HSCs activation and proliferation have been associated with the development of liver fibrosis.
